Cardiac catheterization revealed elevated right ventricular pressure up to 93% of left ventricle.

Repair of a unique sinus of Valsalva defect in an infant.

Sinus of Valsalva aneurysm is a rare disease characterized by the partial elevation of the aortic root. Few reports are available on the surgical treatment for infants. We report the repair of an extremely rare case of a sinus of Valsalva defect with a ventricular septal defect and right ventricular outflow tract stenosis in an infant.

[Aortic Regurgitation and Stenosis Associated with Ventricular Septal Defect in the Elderly;Report of a Case].

A 63-year-old man had ventricular septal defect (VSD) and had been followed up without heart failure. Recently, he had palpitation caused by atrial fibrillation and the echocardiography revealed moderate aortic valve regurgitation and stenosis with right coronary cusp prolapse due to subpulmonary ventricular septal defect. He underwent patch closure of VSD, aortic valve replacement with mechanical valve, and maze procedure.

Late Period Rastelli Take-Down and Arterial Switch Operation After Rastelli Operation.

The Rastelli operation is a useful technique for treating the transposition of the great arteries. However, conduit stenosis of the right ventricular outflow tract is a late complication of the procedure. We report the case of a 35-year-old man for whom an arterial switch operation was performed to treat conduit stenosis and improve ventricular arterial alignment 28 years after he underwent a Rastelli operation to treat transposition of the great arteries with a ventricular septal defect.

[Open Aortic Arch Surgery for Type Ⅰ Endoleak after Thoracic Endovascular Aortic Repair Using Fenestrated Stent Graft;Report of a Case].

Thoracic endovascular aortic repair (TEVAR) has become a major procedure for thoracic aortic aneurysm and its indication is expanding. On the other hand, TEVAR specific complication is rather critical and its treatment is of increasing interest. Especially, open repair after TEVAR is sometimes demanding and case based strategy is mandatory.

Surgical and endovascular treatment of a bilateral deep femoral artery aneurysm.

We report the rare case of a 68-year-old man with a bilateral deep femoral artery aneurysm. Right-sided rupture was treated via plug embolization of the right deep femoral artery and ligation. In the following year, Viabahn® stent grafts were placed in the left superficial femoral artery to relieve occlusion and in the left deep femoral artery to treat the left aneurysm.

Surgical treatment of cardiac fibroma in a child with left ventricular noncompaction.

Surgical treatment of cardiac fibroma is rare in patients with left ventricular noncompaction (LVNC). Although several case reports regarding cardiac fibroma have been published, resection in a patient with LVNC has not been described. Here, we describe the surgical treatment of left ventricular fibroma in a child with LVNC.
